Update home screen

The current Klaw documentation landing page serves its purpose but has room for improvement in terms of design, user experience, and information presentation. The following list suggests several enhancements to address these areas.

- Consider replacing the 'Go to docs' button with a 'Get Started' button directly linking to the introductory documentation. This offers a clear starting point for new users.
- To improve the page's visual hierarchy, adjust text size and color to create a hierarchy. Incorporate more whitespace for better legibility and less clutter.
- The presentation of the Key features feels congested. Expanding spacing and restructuring into a card or grid format with a hover effect and clickable card or similar could improve readability.
- Lastly, harmonizing the design elements, such as icons and buttons, with a consistent style will contribute to a more unified and professional aesthetic.
